A complete pipeline from URL to permanent storage.
Paste any URL or upload a document. Permavault captures the page as it exists right now: content, screenshot, PDF rendering, and a technical record of how it was retrieved.
Your capture lives on Arweave, a network of hundreds of independent nodes worldwide, funded by a long-term storage endowment. Designed for permanence, not monthly invoices.
See exact file size and Arweave storage cost before you commit. No hidden fees.
Source adapters are modular npm packages. Add new content types or build your own.
Power users get a full CLI. Curators get a clean web dashboard. Same engine underneath.
Archive thousands of URLs via CSV. If something fails, retry without re-downloading.
Drop a link to any public web page, or upload a document. Permavault detects what it is and prepares the capture.
See what will be captured and the exact one-time price in USD before you commit. No surprises, no subscriptions.
One click fingerprints your capture and stores it on Arweave. You get a permanent link and a verifiable record anyone can check, today or years from now.
Captures complete in seconds. Permanence takes one click.
Permavault uses a plugin system. Each source is an independent adapter. Install only what you need.

This is a real evidence package from a real capture of this very page. Download it and check every proof yourself with standard tools. No signup, no Permavault account, no trust required.
Hand it to opposing counsel, an expert, or a judge. A plain-English guide inside every package walks them through it, and everything verifies offline with free standard tools: your evidence keeps verifying even if Permavault disappears.
unzip permavault-sample-evidence.zip && bash verify.shChecks the file hashes, the Ed25519 signature, and the permanent Arweave copy. Needs only shasum, openssl, and curl.
Every capture is fingerprinted, sealed, and stored on Arweave's permanent network. Pay in USD by card.

Plain-English guides to the rules that decide whether online evidence holds up, with the case law and primary sources cited.
Free to read, no signup. General information, not legal advice.
Often yes, when nobody contests them. The trouble starts when someone does. What courts have actually done with screenshot evidence, why it fails, and what to capture instead.
Read the guide →Chain of custody was designed for physical evidence. What it means for web captures, where screenshots break it, how hashes repair it, and a checklist that holds up.
Read the guide →Posts get deleted fast and phone screenshots get excluded. How lawyers and investigators preserve Instagram, X, Facebook, and TikTok evidence that survives challenge.
Read the guide →Courts have admitted Wayback Machine captures, but only with an affidavit and only when a snapshot exists. Where the public archive fits, where it does not, and what a capture you control has to prove.
Read the guide →Evidence that needs no extrinsic proof of authenticity. What FRE 902 covers, all fourteen categories, how the certification route works, and the three things it does not do.
Read the guide →Permavault is AGPL-3.0 licensed and built in public. Self-host it, fork it, extend it with new adapters. Contributions welcome.
